A process for producing a vinylidene fluoride copolymer, comprising the step of copolymerizing a mixture of monomers containing a polymerizable double bond comprising:
(A) vinylidene fluoride, and
(B) a fluorine compound represented by the formula:
CH₂=CH-Rf (I)
wherein Rf is a perfluoroalkyl group having 1 to 12 carbon atoms,
with the content of (B) being 0.1 to 50 % by weight, in the presence of a radical polymerization initiator. A vinylidene fluoride copolymer having excellent flexibility, impact resistance and cold resistance together with the good characteristics inherently possessed by polyvinylidene fluoride can be obtained.
一种生产
偏氟乙烯共聚物的工艺,包括将含有可聚合双键的单体混合物进行共聚的步骤,其中包括
(A)
偏氟乙烯,和
(B) 由式表示的
氟化合物:
CH₂=CH-Rf (I)
其中 Rf 是具有 1 至 12 个碳原子的
全氟烷基、
在有自由基聚合
引发剂存在的情况下,(B)的含量为 0.1%至 50%(按重量计)。这样就可以得到一种具有极佳柔韧性、抗冲击性和耐寒性,并具有聚
偏氟乙烯固有的良好特性的
偏氟乙烯共聚物。
